◆ addBranch() [2/2]

StatusCode CP::RNtupleFieldHelpers::ContainerProcessor::addBranch	(	TTree &	,

overridevirtual

Add one branch to the output tree.

This function is used during the setup of the output tree to create one branch in it, from one specific auxiliary variable. The type of the variable is figured out at runtime using the auxiliary store infrastructure.

Parameters

tree	The tree to create the branch in
auxName	Name of the auxiliary variable to create the branch from
branchName	The name of the branch to create in the tree

Returns: The usual StatusCode values
